Christie Brinkleyis selling her $2.8 million beach cottage in Sag Harbor after losing both of her parents, who lived there, Page Six has exclusively learned. The model sent out an e-mail to friends saying, “I wanted to let you know I have just placed my waterfront escape on the market with Elliman . . . but it’s such a special place I hope it will go to someone SPECIAL.” The three-bedroom house on West Water Street overlooks Sag Harbor Cove. A rep for Brinkley told us, “She is selling that house because both her parents, Marjorie and Don, lived in that home and they both sadly died last year. It is a beautiful place, but it is now empty, and she also owns a couple of properties up the road.”
